      Problem number 2 has been resolved. thank you.
      However, problem number 1, 4 is still not resolved.
      The Bluetooth phone app is not updated.
      After the cell phone is connected to the android device via bluetooth,
      the phonebook list synchronizes very well.
      However only if the first digit of the phone number
      in the synchronized and displayed phone book list is 0
      the first digit of 0 is not displayed.
      Also the sort order of the Korean phone book list is Korean
      "ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅍ, ㅎ"


      Additionally, issue 1 is still not resolved.

                              There is a problem where the UI server cannot be updated in the App Store.

                                        1. Проверьте в заводских настройках какой режим камеры заднего хода у вас установлен.
                                        2. Попробуйте переключить этот режим на противоположный (перезагрузка) и затем снова обратно в тот режим который вам нужен (перезагрузка)

                                          This was resolved with the UI seuver update, which continued to not work. The problem occurred because the UI server was not updated. Please note.
                                          It's worked out fine for now

                                            14 days later

                                            Is the number 3 issue (mode button) issue resolved. Im using test 18 also experience the error, will it solved by updating server UI?

                                              hafiz_tahir
                                              It seems to have been resolved in the most recent update, Test18.

                                                Trouble how you resolve the Server UI update error? I have the same error as you experience. Data error

                                                    hafiz_tahir
                                                    Setup>System>Applications, Click on the top right icon ︙, then click the Show system option.
                                                    Find UI Server, then click UI Server>Storage & cache>CLEAR STORAGE.
                                                    Afterwards, proceed with the UI server update.




                                                        Trouble still, i cannot update the server UI. Will post the pic later

                                                            hafiz_tahir It would be better to ask the development team.

                                                              And clear the download list.
                                                              Sometimes if the download was interrupted you can't start it again. You fitst have to delete it from the download list
